There are several red wines from Tuscany, Italy that don’t follow the DOC system and rarely use sangiovesse as their base grape. These wines, often made with cabernet sauvignon or merlot, have become known as Super Tuscans. They are some of the most prized wines from Italy.
Acidity
Acidity in wine is the level of acid that the wine contains. Wines with more acid in them taste more tart or sour.
